I would recommend against it. I had a Hyptertech with the 95 Formula I had and it ran worse with the HPP tuning than stock. Go to www.carputing.com and buy a copy of LT1Edit and tune it yourself. You'll be much happier with the results. It'll take you a little longer because you'll have to learn exactly what is going on with your engine, but in the long run that's a good thing.

Hypertech leans out the AFR a bit, but not by much. On lt1 cars there's no way it could go from a 11.8 to 15 or even 16.
Also, it does not advance the timing. It actually retards it a couple of degrees. (probably to reduce knock retard)
